4. Hardware Description

4.1 LED Functions

- The red light is on to indicate that the HEV-2KW is powered on normally.

- The green light keeps on to indicate that STA is connected to WIFI network and

blinks rapidly to indicate RTMP push normally.

- The yellow light blinks to indicate HEV-2KW works in AP WI-FI Mode.

- The red and green lights flash alternately several times to indicate the factory

settings are being restored.

4.2 Configuration Button

- Hold down the button about 3s to switch the WI-FI working mode between AP and

STA. The yellow light blinks to indicate the device works in AP mode; while the green

light keeps on means STA WI-FI mode.

- Hold the button for 15s to restore the factory settings.

5. Connection Configuration

5.1 Connect to Network

Step 1: Plug the included USB cable into the HEV-2KW to power on it.

Step 2: Open your wireless networking utility on your PC or mobile device to search

SSID called "HEV-2KW" and access to it by the password "12345678". This step is

only required in AP WI-FI mode.

Step 3: Set IP address of your PC, Navigate to 5.2 to see how to set the IP address of

your PC. Then open a web browser and enter the network’s IP address. In AP mode,

the default IP address is “192.168.1.252”; while in STA mode, please login to the WEB

UI by IP address that the router assigns to the HEV-2KW. Make sure your device is in

the same network domain with HEV-2KW.

Step 4: Login to the interface with the default user name and password as “admin”.

Step 5: Navigate to Network Configuration interface to enter the network name (SSID)

for router network and the password to access it; or choose “refresh” for available

wireless networks, select your network SSID, enter the password and then click

“Save”.

Step 6: Hold the button of HEV-2KW for about 3s until the status of LED changes to

switch the WIFI mode as STA. LED indicator usually turns red first and then turns

green when STA is successfully connected to the network. Do not keep pressing the

button because the HEV-2KW will be restored to factory settings after pressing for

more than 15 seconds.

Step 7: Re-login to the WEB UI via the static IP address that you have set or the IP

address that the router assigns to the HEV-2KW.

5.2 Change the IP Address of PC

→On a Windows PC: Press the +R on your keyboard.

→Enter “control netconnections”in the run box and press “Enter”.

→You should see at least two types of network connections: Ethernet and WI-FI.

Double-click the active network connection.

→Select “Properties”and double click “Internet Protocol Version 4 (TCP/IPv4)”.

→If you want to enable DHCP, make sure Obtain an IP address automatically is

selected, as well as Obtain DNS Server address automatically; Or you can select Use

the following IP address option and enter the IP address with 192.168.1.xxx (0-255

except 252) and Subnet mask 255.255.255.0. Press “OK” twice to save the

configuration.

Note: The default IP address of the HEV-2KW is 192.168.1.252 for AP Mode so your

computer’s IP should be 192.168.1.xxx for connecting with HEV-2KW. “xxx” can be

any number ranging from 0 to 255 except 252. In AP mode, it is recommended to

enable DHCP when your PC is connected to the encoder. HEV-2KW will

automatically assign an IP address for your PC so you do not need to enter IP

address value manually.

5.3 Login for Configuration

Enter “192.168.1.252” in your browser to open the HEV-2KW's Web administrator

page. Login with the default user name and password as “admin”. Please note that

only in AP mode can you use the default IP address to access the WEB

UI.

*User name: admin *Password: admin
